Changes in abutment tooth mobility by wearing parital denture: a continued report.
Follow-up measurements of the abutment tooth mobility were carried out to examine the mobility changes for a long period of 12 to 14 years. The subjects were 6 patients, having 12 abutments and they were wearing mandibular unilateral distal extension partial dentures of the same design. These results were as follows: The tooth mobility of the abutment hadn't increased exclusively by the wearing of the distal extension denture over a 10-year period. Among the 12 abutments, 7 abutments showed nearly the same degree of mobility as the initial level, and the mobility of the other 4 abutments increased slightly. However, one abutment alone was extracted because of severe increased mobility. There was an extremely slight difference in the mobility between both abutments and the mobility of each abutment presented nearly the same amount. Also the tendency in the mobility change indicated a similar pattern. The long-term prognosis of mandibular unilateral distal extension partial denture, of the most common clasp design, presented a favourable state during the 12 to 14 years, judging from the changes in the abutment mobility.

Lack of significance of increased tooth mobility in experimental periodontitis.
This experiment was carried out in order to study the rate of progression of experimentally produced periodontal tissue breakdown in teeth which prior to the placement of cotton floss ligatures either had a normal or a permanently increased tooth mobility. Six beagle dogs were used. Trauma from occlusion of the jiggling type was produced on test teeth using a model previously described. Four months later experimental periodontal tissue breakdown was induced around both control and test teeth by placing cotton floss ligatures around the necks of the teeth. The ligatures which were exchanged once every 4 weeks during a 4-month period were replaced at the level of the gingival margin. Tooth mobility measurements and radiographic examinations were performed on Days 0, 30, 60, 90, 120, 160, 240 and 300. One dog was killed on Day 120 and the remaining 5 dogs on Day 300. Biopsies of the test and control teeth were fixed in formalin, decalcified, embedded in paraffin and mesiodistal sections cut with the microtome set at 4 micron. The results demonstrated that the degree of periodontal breakdown, initiated and maintained by ligature placement and plaque accumulation, was similar around teeth with a wide periodontal ligament space and in teeth with a normal width of the periodontium. In other words, progression of the plaque-associated lesions appeared to be unrelated to the width of the periodontal ligament space, i.e., to the degree of horizontal tooth mobility.

Splints made of wire and composite: an investigation of lateral tooth mobility in vivo.
In 103 posttraumatic splints, later tooth mobility was measured with Periotest immediately before and after the routine splint removal. The splints were made of composite resin and an 0.017 X 0.025" orthodontic steel wire. 481 teeth were measured. A statistic evaluation revealed that the immobilisation effect did not exceed normal tooth firmness. Fixation to one neighbouring tooth had less effect than fixation to two. Adjacent tooth gaps reduced the effect. Splint extensions had no influence. With the use of the Periotest device, more than 50% of all teeth with a true mobility of 20 Periotest-units or more were detectable as mobile in spite of the fixed splint.

In vitro analysis of the initial tooth mobility in a novel optomechanical set-up.
An optomechanical set-up was developed to accurately measure displacement/force curves of the initial tooth mobility in vitro. The system presented is capable of recording all six components of a tooth movement resulting from an applied orthodontic force system, and consists of a laser diode-based optical part and a six degree of freedom mechanical part. Three laser diodes were mounted in orthogonal arrangement on the tooth of a specimen and their light (lambda = 670 nm) was focused on the surfaces of three position sensing detectors. The laser beams thus defined a cartesian rigid body coordinate system and the movements of the tooth could directly be derived from the movements of the laser spots on the surfaces of the optical detectors. The force system was applied and simultaneously measured via a three-dimensional force-torque transducer mounted on a six-axis positioning table. Measuring accuracy of the tooth displacements was in the range of 9.0 microns and 0.022 deg for translations and rotations, respectively. Resolution and accuracy of the mechanical system was approx. 0.02 N for the measurement of forces and 0.5 Nmm for torques. Displacement/force diagrams of the specimen of a swine's mandible are presented, showing the relationships between applied force system and tooth displacement of the lower first premolar. The accuracy reached proved to be sufficient for the verification of numerical (Finite Element) models of the initial tooth mobility.

Familial ogee roots, tooth mobility, oligodontia, and microdontia.
The term ogee is proposed to describe dome or onion-shaped incisor roots as presented in a family study. A case of ogee permanent upper incisor teeth associated with microdontia, oligodontia, and tooth mobility is described. Forty-seven members of the proband's family were examined. The dental abnormalities were found to be of an autosomal dominant pattern of inheritance.

Measurement of tooth mobility in children using the periotest.
This study investigated the use of the periotest for measuring tooth mobility of upper permanent incisor teeth in children. A total of 160 children, with equal numbers of boys and girls aged between 9 and 16 years had two periotest readings made on their four upper incisor teeth. In all 1,280 measurements were collected and analysed. The results showed that the second periotest readings were statistically significantly higher than the first. Periotest readings were lower for girls than boys of the same ages. The periotest may have a place as a diagnostic tool in paediatric dentistry and dental traumatology, however, further research is necessary before the periotest can be used to assist in the diagnosis and assessment of healing of traumatised teeth.

Dentinogenesis imperfecta: influence of an overdenture on gingival tissues and tooth mobility.
Case report of a child demonstrating severely-worn primary dentition with dentinogenesis imperfecta is presented. Overdentures were fabricated in order to preserve clinical crowns, re-establish the clinical dimension of occlusion and provide esthetics. The patient underwent monthly recall visits for a 6-month period, during which most rapid changes concerning the gingival tissues and tooth mobility were expected.

[Tooth mobility following treatment with removable appliances].
After a therapy with removable appliances all the teeth showed an increased loosening degree, that means tooth mobility, in comparison to an untreated control group. All the measured patients had been in the retention phase after an average treatment time of 4 years in cases of male patients and 3.8 years in cases of female patients.

The use of removable partial denture splints in the treatment of postsurgical tooth mobility.
The theory and clinical use of removable partial denture splints has been offered as a tenable solution to the problem of postsurgical tooth mobility. The close cooperation of the periodontic and prosthetic specialties is in many cases vital to the ultimate success of treatment and longevity of the dentition. Although not presented as a panacea, it is hoped that clinicians will bear this clinical entity in mind as an option in the treatment of periodontally debilitated dentitions.

Stress distribution and abutment tooth mobility of distal-extension removable partial dentures with different retainers: an in vivo study.
Three types of retainers (wrought wire clasp, Aker's cast clasp, and conical crown telescopic retainer) designed for distal-extension removable partial dentures (RPDs) were assessed in two Kennedy class I patients' mouths. The assessment, included the ratio of denture base shearing load and mobility of the terminal abutments when loaded on a free-end RPD occlusal surface. The mean values of denture base shearing ratios of wrought wire clasp, Aker's clasp and conical crown telescope were 60, 42 and 20%, respectively. The abutment mobility of the three types of retainers were all within the 'mobile ability area' except the wrought wire clasp for patient A's right side. The greatest tooth mobility was observed with the wrought wire clasps, followed by Aker's clasp and the conical crown telescopic retainer. From the analysis the following was concluded: (i) different retainers do influence the occlusal load distribution; (ii) the occlusal load distributed to the free-end saddle is closely related to the connecting rigidity of the retainer; (iii) mucosal support has an indispensable role in sharing the occlusal load with various retainers, even the rigid telescopic retainer.

[Studies with the HSE-digital periodontometer on tooth mobility and for checking of clinical degrees of mobility].
The mobility of normal teeth and teeth with periodontal lesions could be measured by means of the newly constructed HSE-digital-periodontometer and specially developed measuring head. After obtaining norm values, measurements of pethological changes allowed us to determine to what degree the clinically increased mobility of teeth was subject to subjective influences (range of error 36.5 to 70.5%). These results suggest that the scale of clinical grades of tooth mobility be increased to 5 altogether and that practical objective measuring apparatus be developed especially for dental practice.

[Tooth mobility and containment].
Periodontal destruction often leads to tooth hypermobility. In the presence of jiggling forces, traumatic occlusion can provoke a progressive mobility, and in certain cases, accelerate the periodontal destruction in presence of periodontitis. Treatment of infection alone is enough to stop the periodontal destruction. If the mobility becomes progressive, or if the hypermobility impedes the masticatory function of the patient, an occlusal adjustment and/or a splint are valuable to assure the longevity of a tooth. Tooth mobility is the physiological adaptation of the periodontium to the traumatic occlusion, and is, in itself, not an indication for splinting.
